SUN-OBSERVING DEVICE.

Application led May 10, 1926. Serial No. 108,181.

The invention aims to provide a new and improved device which will permit thorough examination of the sun in such manner as to determine to a greater extent than has heretofore been determined, the actual facts concerning it, and by virtue of the results obtained. will convey valuable information with regard to the influence of the sun upon all other planets, particularly the earth. The information so obtained will be of such a nature as has never before been obtained from any other source.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a perspective view of the complete device with the exception that partof the side wall of the booth for the observer, is broken away to show parts within the same.

Figure 2 is an enlarged vertical sectional view through the vision-tube carrier and as sociated parts.

Figure 3 is a bottom plan view of the parts shown in Fig. 2, partially broken away.

Figure 4 is a horizontal sectional view on line 4-4 of Fig. 2.

Figure 5 is a longitudinal sectional view through the vision tube.

In illustrating the invention, a number of details have been shown, which details have been utilized in the construction of a rather crude working device, and while I have followed these details in giving the present disclosure of the invention, it is to be understood that I am by no means restricted to them.

The numeral 6 designates a horizontal base upon which a booth 7 rests, said booth being provided with castors or the like 8, so that it may be turned upon the base to any desired position. The top 9 of the booth 7 is preferably horizontal and said top is formed with a narrow vision slot 10 which is disposed over a vision-tube 11 within the booth, said tube being preferably about ten or twelve inches above the base 6, whereas it is disposed a relatively great distance from the top 9, and these relative 'distances may be varied as desired and according to the number of hours per day which the sun is to be observed. A carrier 13 is provided for the vision-tube 11 and this carrier 1s adjustably pivoted as at 14, to the lower ends of suitable hangers 15 which depend from the top 9 of the booth 7, wing nuts or the like 16 being provided to hold the carrier 13 and the tube 11 at any desired substantially vertical or inclined position. The operator lies upon the base 6, upon a suitable pallet 17 and with one eye closed, uses the other eye to look through the vision-tube 11 and slot 10 at the sun, and by adjusting the carrier as the sun travels along its path, it may be accurately viewed for a number of hours.

Preferably, the top 9 of the booth 7 is supported by four sectional legs 18 whose sections may be detachably connected by sleeves or other suitable means 19, and the side wall of this booth is formed by a canvas curtain 20, said curtain having an opening 21 through which an observer may enter and leave the booth and through which his legs may project when lying upon the pallet 17. This opening is of course provided with a suitable flap 22 to exclude light and it will be vunderstood that no light is permitted to enter the booth, except that entering through the vision slot 10.

The vision-tube carrier 13 may be of any desired construction to effectively support said tube and to form a shield to protect the observers eyes against the rays of light entering the booth through the slot 10, that is rays which would reach his eyes by a route other than through the vision-tube 11, and it has been found that the rays reaching the eye through this tube, will not be objectionable or injurious to sight.

In the present showing, the carrier 13 includes a rectangular box or casing 23 which is open at its lower side and is formed with a central opening in which the upper portion of the tube 11 is secured. A dome 24 is disposed within this casing and is formed with a central opening through which the tube 11 passes, the top of said dome being held in contact with the top of the casing 23, by a bottom plate 25 which is supported by appropriate cleats or the like 26-27, secured to the inner sides of the casing walls, the lower e'dge of the dome being in contact with said bottom plate. This plate also contacts with the lower end of the vision-tube 11 and is formed with a View opening 28 registering with said tube. A horizontal plate 29 spans the interior of the dome 24 and contacts with the latter near the top of said dome, said plate having an opening in which the tube 11 is secured, so that the plate tends to brace and steady the tube and prevent any angling thereof with respect to the casing 23. Another bracing plate 30 is shown extending across the dome 24, between the plates 25 and 29, the central portion of said plate 30 having a clamp 31 which tightly surrounds and holds a collar 32, said collar surrounding the tube 1l near the lower end of the latter. lVedges 33 are shown inserted tightly between the edge of the plate 30 and the dome 24 to neatly and securely hold said plate and dome in iixed relation, and any relative movement of the dome with respect to the casing 23, is prevented by appropriate bracing plates 34 and 35, secured between and in contact with said casing and dome.

The tube 1l may be composed of separate sections as illustrated in Fig. 5, said sections being designated at 36, 37, 38, 39, 40 and 41. The upper section 36 is provided with a valve or shutter 42 for controlling the light passage 43 of the tube 11, said valve or shutter having an appropriate operating stem 44 provided with a knob or the like 45 by means of which it may be turned. The light passage through this section 36 is preferably small, which is also true of the section 38, whereas the connect-ing section 37 may have a rather large internal diameter, which is also true of the sections 39 and 40. The section 41 is in substantially the form of a bell shouldered at 46 to engage the collar 32, which collar is held by the clamp 31 of the plate 30. An arched cover 47 is preferably provided for the tube section 36, which section projects above the top of the casing 23, said arched cover having an opening through which the stem 44 passes, leaving the knob or the like 45 accessible for adjustment of the valve or shutter 42.

In order that an observer lying upon the pallet 17 may rest from time to time, a shutter plate 48 is preferably slidably engaged with the plate 25, so that it may be slid across the opening 28 to cut off all light from his eyes. The ends of this shutter plate may well engage the cleats 26 and may be provided with downturned guides 49 slidable in recesses 50 of said cleats. If desired, one or more cords such as at 51 may be utilized for sliding the shutter plate 48 into or out of operative position.

By lying upon the pallet 17 and adjusting the carrier 13 so that with one eye, the observer may look through the slot 10 at the sun, he may without any injury or discomfort,

readily study the same, thereby obtaining information of value for reasons hereinbefore set forth. Moreover, by readjusting the device from time to time, the sun may be observed for a number of hours.

In the apparatus which I have successfully used, the base 6 is about six feet square but may be circular and of about six feet in diameter if desired; the legs 18 are each approximately nine feet in length; the top 9 is about three feet square and the slot 10 is three-fourths of an inch wide and about two feet eight inches long; the assemblage of parts shown in Fig. 5 has a total height of five and one-fourth inches, the diameter at the lower end of the member 4l is one inch, and the openings 38-43, are each of about onesixteenth of an inch diameter. The distance between the lower end of this assemblage and the pallet 17 is about ten or twelve inches and this pallet is about two feet by five feet.

The details herein disclosed may be folloWed if desired, but within the scope of the invention as claimed, numerous variations may be made.
